Abstract

The object of the present invention is to provide: a composite molded article formed by integrating a 1 st molded article and a 2 nd molded article, which has high bonding strength and is stable and less in variation in bonding strength between the injections of the molded articles. A composite molded article comprising: a grooved 1 st resin molded article containing at least a resin, a glass fiber, and a laser absorbing material, and having a groove in which the glass fiber is exposed; and a 2 nd molded article disposed adjacent to the surface of the 1 st resin molded article having the groove, wherein the 1 st resin molded article contains 12 to 45 mass% of the glass fiber with respect to the entire resin composition constituting the resin molded article, and 0.25 to 10 mass% of the laser absorbing material with respect to the entire resin composition, and the glass fiber is contained in a specific blending range.

Description

Composite molded article
Technical Field
The present invention relates to a grooved 1 st resin molded article and a composite molded article using the grooved 1 st resin molded article.
Background
In recent years, in the fields of automobiles, electric appliances, industrial equipment, and the like, there has been an increasing trend to replace a part of a metal molded article with a resin molded article in order to meet the requirements such as reduction in carbon dioxide emission and reduction in manufacturing cost. Along with this, composite molded articles formed by integrating resin molded articles and metal molded articles have been widely used. In addition, composite molded articles obtained by integrating molded articles made of the same or different materials have been widely used.
As a method for producing a composite molded article in which a 1 st resin molded article and a 2 nd molded article are integrated, patent document 1 proposes the following: the surface of the 1 st resin molded article containing an inorganic filler is irradiated with a laser beam to form a groove structure in which the inorganic filler is exposed on the surface, and then another resin molded article is brought into contact with the surface, filled, and molded to be integrated therewith.

Problems to be solved by the invention
However, when a groove structure is formed in a resin molded product by irradiation with a laser beam, the state of attenuation due to absorption and scattering of the laser beam changes depending on the shape and the amount of an inorganic filler such as glass fiber or a blending agent that absorbs the laser beam mixed in the resin, and therefore the state of formation of the groove structure and further the bonding state of the composite molded product are affected.
In particular, when it is necessary to suppress the output of laser irradiation for the purpose of avoiding deterioration of the resin portion or for reasons such as facility restrictions, dispersion and/or variation in orientation state of the inorganic filler and/or the compounding agent during molding and injection of the 1 st resin molded article easily affect formation of the groove structure, and as a result, variation in bonding strength occurs, the yield is poor, and a composite molded article with poor productivity may be obtained.
The present invention has been made to solve the above problems, and an object of the present invention is to provide: the strength of the 1 st resin molded article and the 2 nd resin molded article can be maintained when they are joined, and the strength between molding and injection can be stabilized with less variation.
Means for solving the problems

Detailed Description
Hereinafter, specific embodiments of the present invention (hereinafter, referred to as "the present embodiment") will be described in detail with reference to the drawings. The present invention is not limited to the following embodiments, and various modifications can be made without departing from the scope of the present invention.
< composite molded article >
The composite molded article of the present invention is characterized by comprising: a grooved 1 st resin molded article formed of a resin composition containing at least a resin, a glass fiber, and a laser absorbing material, and having grooves in which the glass fiber is exposed; and a 2 nd molded article disposed adjacent to the surface of the 1 st resin molded article having the groove, wherein the 1 st resin molded article contains 12 to 45 mass% of the glass fiber with respect to the entire resin composition, and 0.25 to 10 mass% of the laser absorbing material with respect to the entire resin composition, and satisfies [ { amount (mass%) of the glass fiber contained in the resin composition constituting the 1 st resin molded article x 0.9} + { amount (mass%) of the laser absorbing material contained in the resin composition constituting the 1 st resin molded article x 1.4} ] × { melt viscosity (Pa · s) +360 }/{ average diameter (μm) × 0.8} of the glass fiber contained in the resin composition constituting the 1 st resin molded article is 700 or more and 2500 or less.
Fig. 1 is a schematic enlarged cross-sectional view of a composite molded article of the present invention. The composite molded article 1 includes a 1 st resin molded article 10 having a groove and a 2 nd molded article 20 having a projection. In the grooved first resin molded article 10, glass fibers protrude from the side surfaces in the grooves. The convex portion of the 2 nd molded article 20 is fitted into the groove of the 1 st resin molded article 10 with the groove so as to surround the protruding glass fiber.
Grooved No. 1 resin molded article 10
Fig. 2 is a schematic enlarged cross-sectional view of the grooved 1 st resin molded article 10. The grooved 1 st resin molded article 10 contains glass fibers 11. The grooved 1 st resin molded article 10 has grooves 12 in which glass fibers 11 protrude from the side surfaces and are exposed. A portion of the glass fibers are mounted on the grooves.
[ resin ]
The resin used in the resin composition constituting the grooved 1 st resin molded article 10 of the present invention is not particularly limited as long as it can be removed by irradiation with a laser beam and as a result, the grooves 12 can be formed, and may be thermoplastic or thermosetting. Suitable materials for the resin include, for example, polyphenylene sulfide (PPS), Liquid Crystal Polymer (LCP), polybutylene terephthalate (PBT), polyethylene terephthalate (PET), Polyacetal (POM), Polyamide (PA), and the like.
[ glass fiber ]
The glass fiber 11 of the present invention is characterized in that a part of the resin molded product is removed to protrude and expose from the side surface of the groove formed in the 1 st resin molded product 10 with the groove. The average fiber length of the glass fiber 11 is not particularly limited, but is preferably 0.1 to 5mm, more preferably 0.5 to 3.5mm, and the average diameter is preferably 3 to 20 μm, more preferably 8 to 15 μm in a state before melt-kneading to a resin.
In general, when the glass fibers have the same content (% by mass) and different diameters, the smaller the average diameter of the glass fibers, the more the number of glass fibers present in the same volume, and thus the mechanical properties such as tensile strength tend to be high, but in the present invention, when the average diameter of the glass fibers is too small, the more the number of glass fibers increases as described above, so attenuation due to reflection and scattering of laser light is likely to occur, the removal efficiency of the resin decreases, and the formation of grooves which are sources of the anchoring effect is affected, and therefore, the bonding strength between the grooved 1 st resin molded article and the grooved 2 nd resin molded article may decrease, or the variation in bonding strength between products may become large.
On the other hand, when the average diameter of the glass fiber is too large, it may be difficult to sufficiently improve the mechanical properties of the resin composition itself. From these viewpoints, it is desirable to set the average diameter of the glass fibers within the above-described appropriate range.
The content of the glass fiber is 12 mass% or more and 45 mass% or less with respect to the entire resin composition constituting the grooved 1 st resin molded article. If the amount is less than 12% by mass, even if the glass fiber 11 is exposed from the groove 12, the anchoring effect of the glass fiber 11 to suppress the breakage of the 1 st and 2 nd grooved resin molded articles 10 and 20 may not be sufficiently exhibited.
If the amount is more than 45 mass%, the laser light irradiated for forming the grooves 12 is easily affected by attenuation due to the glass fiber 11, and the bonding strength between the grooved 1 st resin molded article 10 and the grooved 2 nd resin molded article 20 may vary greatly. The content of the glass fiber is preferably 15 mass% or more and 40 mass% or less, more preferably 20 mass% or more and 38 mass% or less, and further preferably 25 mass% or more and 35 mass% or less. The average fiber length and the average diameter can be determined by reading the values of 100 samples in an electron micrograph and determining the average value.
The glass fibers 11 may be used alone or in combination, and may contain glass flakes other than fibers, inorganic fillers such as mica, talc, and glass beads, other additives, modifiers, and the like to such an extent that the effects of the present invention are not impaired.
When the glass fiber 11 exposed in the groove 12 exerts an anchoring effect to suppress the breakage of the grooved 1 st and 2 nd resin molded articles 10 and 20, the glass fiber 11 is suitably bridged between the uneven ridges 13 formed by removing a part of the resin in the groove 12.
[ laser light-absorbing Material ]
In the present invention, by containing the laser absorbing material in an amount of 0.25 to 10 mass% of the entire resin composition constituting the grooved 1 st resin molded article 10, the ease of resin removal (ease of groove formation) during laser irradiation can be appropriately adjusted, and variation in bonding strength can be suppressed. When the amount is less than 0.25 mass%, attenuation due to reflection and scattering of the laser light by the glass fiber is likely to occur, and the state of formation of the grooves is likely to vary, and when the amount is more than 10 mass%, aggregates of the laser absorbing material are generated, and at a position where the laser absorbing material is aggregated to have a high concentration, overheating due to the laser light is likely to occur to generate carbide, and these become fracture starting points in the form of foreign matter, and variations in the bonding strength are likely to occur.
The content of the laser light absorbing material is preferably 0.35% by mass or more and 9% by mass or less, more preferably 0.4% by mass or more and 8% by mass or less, and further preferably 0.5% by mass or more and 6% by mass or less of the entire resin composition constituting the 1 st resin molded article.
The laser light absorbing material of the present invention is not particularly limited as long as it can absorb laser light, and for example, materials such as pigments and dyes can be used.
[ tank ]
The grooved 1 st resin molded article 10 of the present invention has grooves 12 formed on the surface thereof. In the groove 12, the glass fiber 11 is exposed. Then, the groove 12 is formed by removing a part of the resin, and the glass fiber, which is exposed from the side surface on at least the front surface side of the groove and shields a part of the laser light irradiated to the groove, is removed, whereby the glass fiber 11 can be exposed in a state of protruding from the groove side surface by the side surface 12a of the groove 12. By removing at least a part of the glass fiber 11, the anchoring effect at the time of composite molding with another resin molded product can be improved.
In addition, when the composite molded article is obtained by integrating with the 2 nd molded article, at least a part of the end portion of the glass fiber exposed on the surface side is removed in a protruding state, and particularly, the glass fiber at the center portion of the groove is removed, whereby the 2 nd molded article in a flowing state can be easily fitted into the groove, and a high anchoring effect can be obtained.
In the present invention, the surface of the grooved 1 st resin molded article 10 having the grooves 12 is used as a contact surface, and the surface is integrated with the 2 nd molded article 20 to produce the composite molded article 1, but the glass fibers 11 are not exposed in the composite molded article 1.
In the present specification, even when the glass fiber 11 is not exposed in the composite molded article 1, in the mode of removing the 2 nd molded article 20 from the composite molded article 1, as long as the glass fiber 11 is exposed from the groove 12, it is referred to as "the glass fiber 11 is exposed in the groove 12".
In view of effectively obtaining a sufficient anchoring effect by protruding and exposing the glass fibers from the side surfaces of the groove in the composite molding with the 2 nd molded product, the longitudinal direction of the groove 12 is preferably different from the longitudinal direction of the glass fibers 11. In addition, when the glass fiber is mounted on the groove, the bonding effect is further improved.
By providing a plurality of grooves 12 in the grooves 12 formed on the surface of the resin molded article 10, the anchoring effect is further improved. When the plurality of grooves 12 are formed, the plurality of grooves 12 may be formed as separate grooves, or a plurality of concave and convex grooves may be formed at a time in a one-touch input manner. The interval between the grooves may be appropriately set in consideration of ease of fitting the convex portion of the 2 nd molded product, difficulty of dropping the exposed glass fiber, structural strength of the concave and convex portions, and the like.
The plurality of grooves 12 may be arranged side by side with the grooves 12 connected at both ends as shown by the outline, may be formed in a non-intersecting stripe shape, or may be formed in a lattice shape with the grooves 12 intersecting. When the grooves 12 are formed in a lattice shape, the grooves 12 are preferably formed in an oblique lattice shape in which the longitudinal direction is different from the longitudinal direction of the glass fiber. When the grooves 12 are formed in a lattice shape, the grooves 12 may have a rhombic shape.
The length of the groove 12 is not particularly limited, and when the groove 12 is short, the shape of the opening may be a quadrangle, a circle, or an ellipse. In order to obtain an anchoring effect, the groove 12 is preferably long.
The depth of the groove 12 is not particularly limited, and the depth of the groove 12 is preferably deep in order to obtain a higher anchoring effect. When the groove 12 and the 2 nd molded article 20 are joined to form the composite molded article 1, the shallower the depth is, the sufficient anchoring effect cannot be produced between the glass fiber 11 exposed in the groove 12 and the 2 nd molded article 20, and therefore the 1 st resin molded article 10 and the 2 nd molded article 20 with the groove may not be firmly adhered to each other.
< 2 nd molded article and composite molded article >
The material forming the second molded article 20 of the present invention is not particularly limited as long as it is a resin that is in an uncured fluid state and can flow into the groove 12 where the glass fiber 11 is exposed, and may be formed of any of a thermoplastic resin, a curable resin (a thermosetting resin, a photocurable resin, a radiation curable resin, or the like), a rubber, an adhesive, or the like. The same resin as or a different resin from the resin constituting the 1 st resin molded article may be used. The difference here includes the case where the resin which partially constitutes the 1 st resin molded article is contained. In the present invention, different species can exert effects in particular.
In the present invention, the 2 nd molded article 20 has a convex portion which comes into contact with the groove 12, and the convex portion is fitted into the groove 12. The convex portion is preferably disposed inside the groove 12 so as to surround the glass fiber 11.
The 2 nd molded article is laminated on the 1 st resin molded article by injection molding, transfer molding, welding, or the like to form the composite molded article of the present invention.
< relationship between laser-absorbing Material and Components >
In the present invention, the content and average diameter of the glass fiber contained in the resin composition constituting the grooved 1 st resin molded article, the content of the laser absorbing material, and the melt viscosity of the material constituting the 2 nd molded article and the bonding strength of the obtained composite molded article mutually affect each other.
As described above, for example, when the diameter of the glass fiber included in the grooved 1 st resin molded product is small and the content is large, the laser beam attenuation is not favorable for the groove formation, but in this case, the removal of the resin by the laser beam can be promoted and the influence of the laser beam attenuation can be reduced by increasing the content of the laser beam absorbing material within a range in which the problem of the aggregation does not occur.
In addition, when a material having a low melt viscosity is used as the material constituting the 2 nd molded product, the groove formation state is unfavorable, but it may be advantageous from the viewpoint of the joining strength to make the convex portion of the 2 nd molded product easily fit into the groove.
On the other hand, from the viewpoint of product design and appearance, when the grooved 1 st resin molded article and the grooved 2 nd molded article are blended, the amount of the laser absorbing material such as glass fiber or carbon black contained in the material constituting the 2 nd molded article may be increased depending on the requirements of mechanical properties and colors of the grooved 1 st resin molded article and the grooved 2 nd molded article, and in this case, the content of the additive in the material constituting the 2 nd molded article is increased, so that the melt viscosity is increased, and the material becomes hard to be fitted into the groove portion of the grooved 1 st resin molded article, and therefore, the joint strength may be disadvantageous.
In the present invention, considering the mutual influence of the laser absorbing material and the respective components, the relationship between the amount of glass fiber contained in the resin composition constituting the grooved 1 st resin molded article and the average diameter, the amount of the laser absorbing material added, and the melt viscosity of the material constituting the 2 nd molded article is such that a value obtained by "[ { the amount (mass%) of glass fiber contained in the resin composition constituting the grooved 1 st resin molded article x 0.9} + { the amount (mass%) of laser absorbing material contained in the resin composition constituting the grooved 1 st resin molded article x 1.4} ]x { the melt viscosity (Pa · s) +360 }/{ the average diameter (μm) × 0.8 }" of glass fiber contained in the resin composition constituting the grooved 1 st resin molded article is 700 or more and 2500 or less, preferably 1000 or more and 2300 or less, more preferably 1200 or more and 2100 or less.
In the present invention, the term "melt viscosity (Pa · s)" means 1000sec measured in accordance with ISO11443 for a material constituting a molded article-1The melt viscosity at the time of measurement is +30 ℃ in the case where the main component is a component having a melting point similar to a crystalline resin, based on a component (thermoplastic resin or the like) mainly contained in a material constituting a molded article; when the component is a component having no clear melting point like an amorphous resin, the glass transition temperature is +120 ℃.
